Welcome back to Answers of the Day — our daily Jalopnik feature where we take the best ten responses from the previous day's Question of the Day and shine it up to show off. It's by you and for you, the Jalopnik readers. Enjoy!

We are not recommending you buy any of these cars. Well, you should definitely buy an E39 M5 and a VW Phaeton, but that's about it. Consider finding yourself a Yakuza-spec Infiniti M45, or a C5 Z06 Corvette if you want a great used bargain. These cars are quite a different matter. Let's just say there's a good reason why they depreciated so much.

I know what a 70,000 mile QP feels like. It feels like trash. There's a reason a 5 year old QP sells for $25,000 at a wholesale auction. The leather may feel nice, the engine may sound good, it may be pretty and it may be fast, but I have loads of experience with exotic cars and these cars do not age well at all in terms of fit, finish, and quality. They are unreliable, crazy expensive to repair and maintain, and, in my experience, bits literally fall off them.

So don't go out and think that an old Maser or a ten-year-old Mercedes AMG makes a good used buy. Maybe check our ten fastest cars for $10,000 list for some more sensible advice.

10.) 2003 BMW M5 — Down $54,000

The legendary E39 M5, a member of the Jalopnik Fantasy Garage, has lost a total of $54,000, falling from around $71,000 to just $17,000. That figure counts more when you consider that the E39 is, in fact, a priceless work of automotive art.

9.) 2004 Maybach 57 — Down $200,000

You can buy one of these early Rolls-Royce competitors for just over $100,000. It stickered for $305,500 almost a decade ago. Despite the massive $200,000 drop, an old Maybach 57 has only lost two thirds of its value. That's chump change in this group.

7.) 2006 Cadillac STS-V — Down $57,000

The STS-V is a reasonably handsome, rear-wheel-drive V8 luxo-sedan that is quiet and happy to smoke its rears all day. That's not why it's on this list though. It fell from a list price of $77,090 to around $20,000.

5.) 2005 Maserati Quattroporte — Down $70,000

The Quattroporte has the distinction of depreciating the fastest out of any car here, with some 2012 models already losing $35,000 off their original MSRP. First-generation cars, which would likely fall apart in your hands, went from around $95,500 originally to $25,000 now.

4.) 2003 Porsche Cayenne Turbo — Down $70,000

We're surprised that the 450 horsepower Cayenne Turbo has dropped from around $90,000 to about $20,000. It was such a good looking car, and so many people need supersports SUVs in their day-to-day lives. /sarcasm

3.) VW Phaeton W12 — Down $75,000

We were actually hoping that the 444 horsepower W12 Phaeton would get the number one spot on this list. Their base MSRP was $94,600 and now you can get one for around $18,000. We love Phaetons. They are among the most rigorously precise vehicles engineered in recent decades.

1.) 2003 Mercedes-Benz CL55 AMG — Down $99,000

AMG Mercedes-Benzes are the undoubted kings of depreciation, with ruinously expensive (and frequent) trips to the mechanic, and a disposable quality that makes last year's model worthless to any self-respecting plutocrat.

We found one of these pretty S-Class coupes that had lost 86% of its value, dropping from $114,600 to $15,500. Damn.
